Abstract
A method for bonding composites together that is fast and effective, and can be applied to any structure regardless of its size and shape, and its related product are disclosed. The method comprises first subjecting at least a part of a composite work piece to a low-temperature, atmospheric pressure plasma, wherein the reactive gas from the plasma is projected out of the device and onto the surface of the composite work piece, then applying an adhesive to the surface of the treated composite work piece, and joining the composite work piece together with a second work piece. The adhesive may be cured such that it forms a strong, permanent bond. The atmospheric plasma delivery device may be translated over the composite surface by hand or with a robot. The plasma device may be self-contained and portable, and can be moved to a location that is convenient for treating the composites.
